For protecting wildlife from electrocution by high voltage components, dielectric covers are used to cover fuse cutouts, insulators, or other high voltage components. The cover includes through-holes for receiving retaining pins to secure the cover in place. The holes are the weak link in flashover prevention since the holes form an air gap, which has a breakdown voltage lower than that of the cover material. To prevent a bird's wing or a squirrel's tail from directly covering the hole in the surface of the cover, an arched or tubular hood is formed around each hole to block the bird or squirrel from directly covering the hole, reducing the risk of a flashover through the hole. The hoods extend out about 1-1.5 inches to essentially add a 1-1.5 inch air gap between the animal and the hole without enlarging the cover.

Modular wire management systems may include connectors configured for mounting on a base and for connecting to extension members, thereby connecting extension members to one another, to form a framework for managing and routing wires at one or more heights above the base. The systems may further include securing members configured to secure wires to the framework. Modularity may be provided in that every extension member may be connectable to every connector, and every connector may be connectable to every extension member. Connections may be achieved by secure but detachable friction fit, providing both stability and easy reconfigurability. Flexibility of configurability may be provided by a wide range of different kinds of connectors. Connectors may be provided with non-electrically conductive mounting portions for connecting to the base. Apparatuses and methods are also provided.

A wound electrical component includes a wound body comprising a plurality of wound layers of an electrically insulating material around a longitudinal axis of the body. The component also includes at least one printed electronics sensor consisting of printed circuits on a flexible substrate. Each sensor is interleaved between two of the wound layers of the wound body.

A stretchable structure comprises or is configured to receive a conductive path and an interface region. The interface region comprises a peripheral line comprising at least one inwardly curved portion, such as an inverted teardrop or a fjord like recess pointing essentially towards the center area of the interface region. The interface region is arranged to receive said stretchable conductive path via said inwardly curved portion of said peripheral line of said interface region. In this way the interface region minimizes strains or other twisting or stretching forces directed to the conductor entering into the opening of the inwardly curved portion of the interface region.

A universal cable system includes a cable, which may include a keyed profile and an optional, integrated pull cable for low-voltage applications in residential and commercial structures, both old and new construction, which may further includes a connector, which does not require individual splicing of the wires from the cable. The connector may be self-crimping or crimped with a tool. During installation of the connector onto the cable, conductors in the connector may be simultaneously spliced to the wires of the cable during crimping.

A safety device is configured to be attached to components in an electrical substation to provide a physical and visual barrier between de-energized components and energized components in the electrical substation. The safety may include a safety barrier board formed from an electrically insulating material and configured to be attached to fastening devices that attach the safety barrier board to components in the substation. Each fastening device may be an inverted-J-hook configured to be attached to a surface of the safety barrier board or a coupling link attached to a variable length fastening component and an attachment hook.

An electrical component cover includes a central portion, a first end portion and a second end portion and one or more flexible portions between the central portion and the first end portion or second end portion to enable the electrical component cover to flex and thereby facilitate varying geometries in power lines attached to insulators.

A lighted artificial tree includes a first tree portion including a first trunk portion, first branches joined to the first trunk portion, and a first light string. The first trunk portion has a trunk connector and a first trunk wiring assembly, the first trunk wiring assembly is electrically connectable to the first light string and the trunk connector, and at least a portion of the first wiring assembly is located inside the first portion. The second tree portion includes a second trunk portion, second branches, and a second light string. The second trunk portion has a trunk connector and a second trunk wiring assembly, the second trunk wiring assembly electrically connectable to the second lighting string and the trunk connector. The second tree portion may be mechanically coupled and electrically connected to the first tree portion by coaxially coupling the first trunk portion to the second trunk portion.
